IMPROVEMENT IN LOOM-SHUTTLES.

Specification forming part of Letters PatentNo. 221,415, dated Novemberl1, 1879; application lcd May 5, 1879.

To all whom it may concern.-

Be it known that I, HENRY J. MILLER, of Lowell, in the county ofMiddlesex and Gommonwealth ot' Massachusetts, have invented new anduseful Improvements in Loom-Shuttles, of which the following is aspecification.

My invention4 consists in a catch-lever pivoted to the head of thespindle,and adapted to be released from and engaged with a groove in thebobbin-head by the inner and out-er arms respectively of said leverstriking the top spring, in combination with the shuttlebody, thespindle, and said spring, as hereinafter described.

In the accompanying drawings, Figure 1 is a plan of a part of aloom-shuttle provided with my invention, with a bobbin. Fig. 2 is anelevation of the same, a part of the shuttlc-body being broken away toshow the head of the spindle and the catch and the bobbinhead, thelatter being in section. Figs. 3 and 4 respectively represent anelevation and a' plan of my invention applied to the head of a"shuttle-spindle to retain a bobbin having an y externallygrooved head.

A is the shuttle-body; B, the flat top spring,l which (secured to theshuttle-body by the screw C) presses on the head D of the spindle E, andkeeps the latter from rising when the shuttle is thrown in the loom.

The spindle is solid, and may be provided witha iiange, F, to steady achambered bobbin, G,'Figs. l and 2, on the spindle, and is pivoted at Hto the shuttle-body.

The parts above named have the usual operation, and, except ashereinafter specified, the usual construction.

The part I of the spindle-head between the head proper, D, and thespindle E is slotted in the center vertically at K, and receives a bentcatch-lever, L, pivoted at M. The slot K extends back into the headproper, D, and

the outer upper end of the catch-lever L reaches up through the head Dand bears against the bottomvof the top spring, B, just back of theupper corner of saidhead, upon which upper corner the spring also bears.The inner end of the lever L extends to the right, and is provided Witha vertical catch, N, which enters a groove, O O', in the head of thebobbin G G when the spindle is down.

The annular groove may be on the inside of the bobbin-head O, in Figs. 1and 2, in which case the inner end of the catch-lever L is above thepart I; or the groove may be on the outside of the bobbin-head O', inFigs. 3 and 4, in which case the inner end of said lever Lis oft'- setat P through the slot K, so as to be below the part I 5 but in either ofsaid cases the catch N is thrown up by the pressure of the top spring,B, on the outer or left end of the catch-lever into an annular grooveformed in the head of the' bobbin. This is the position of the catchwhen the spindle is down.

When the free end of the spindle is raised to remove the bobbin from thespindle the inner end ofthe spring strikes the catch-lever on the inneror right side of the pivot M and pushes the catch down out of the groovein the bobbin-head, so that the bobbin may be drawn oft' the spindle inthe usual manner.

A slight projection, R, may be placed on the top of the lever L for theend of the spring B to strike against; but this will not be nocessary ifthe pivot M be placed near enough to the pivot H to allow the spring tostrike said 'lever L between said pivot M and catch N when the spindleis raised.

It will be seen that the catch-lever is oper-V ated wholly by the topspring, both in engaging with and in releasing the bobbin; that itsaction is nevertheless positive, because, if the spring be strong enoughfor its ordinary use, it will be much stronger than is necessary to movethe lever, and so far as the operation of the lever is concerned isinflexible; that this device allows the use of the top spring commonlyused in loomshuttles, and does not require any additional cutting awayof the wood of the shuttle.

I claim as my invention- 1. A bobbin catch-lever, L N, pivoted to thehead of the spindle E, and adapted to be reA leased from and engagedwith a groove, O O', in the head of the bobbin Gr G' by the inner andouter arm, respectively, of said lever L N striking the top spring,B,incombination with head Of the spindle E, and adapted to be eutheshuttle-body A, the spindle E, and said gaged with a groove, O O', inthe head ofthe spring, as and for the purpose specified. bobbin G G bythe' outer arm 0f said lever 2. A bobbin catch-lever, L N, pivoted tothe striking the top spring, B, in combination with head of the spindleE, and adapted tO be rethe shuttle-body A, the spindle E, and saidleased from a groove, 0 0', in the head of the spring B, as and for thepurpose specified. bObbin G G bythe inner arm of said leiter strikingthe topspring, B,in eombinationwith HENRY J MILLER' the shuttle-body A,the spindle E, and said spring B, as and for the purpose specified.

3. A bobbin catch-lever, L N, pivoted to the Witnesses:
